# Overview

> Register and reference customer KYC records for onramp, offramp, and withdraw orders.

When the `partner_kyc` feature flag is enabled for your partner account, every onramp, offramp, and withdraw order **must** reference a previously-registered customer KYC record via `kyc_id`. Register your KYC records ahead of time, then pass the `kyc_id` on the order.

<Note>
  Customer KYC records are append-only — they can be created, updated, listed, and fetched, but **not deleted**. The `kyc_id` is retained as an audit link on every order that referenced it.
</Note>

See [KYC Management](/guides/partner-customer-kyc/kyc-management) for the endpoint reference, and [How to use in orders](/guides/partner-customer-kyc/how-to-use-in-orders) for attaching `kyc_id` to onramp, offramp, and withdraw requests.
